Logo
The bWalletX logo is a single gold b: the Bitcoin Corporation flag-top b, gold on dark.
No X in the mark
Section titled “No X in the mark”The mark is the b alone. The X lives in the word bWalletX, never inside the mark. Decided 4 Oct 2026.
Geometry
Section titled “Geometry”The master is logo.svg in the bwalletx-site repo, drawn on a 23 8 74 100 view box.
- Stem: a polygon with points
45,12 45,72 27,72 27,30. The slanted top edge, from (27,30) up to (45,12), is the flag. - Bowl: a circle at (60,72) with radius 33.
- Counter: a circle at (60,72) with radius 15, cut out of the stem and bowl with a mask.
- The join. On 23 Oct 2026 the stem was ended at y=72, the bowl’s centre line, so the stem meets the bowl’s vertical tangent with no step.
Gold gradient
Section titled “Gold gradient”A vertical linear gradient from y=12 to y=105:
| Stop | Colour |
|---|---|
| 0 | #FFE58A |
| 0.55 | #FFD24D |
| 1 | #C98F00 |
Clear space
Section titled “Clear space”Leave space around the mark on every side. Don’t let text, edges or other marks crowd it. In headings the mark takes the place of a letter, so normal letter spacing applies (see Type).
Minimum sizes
Section titled “Minimum sizes”- 16px: favicon. The smallest the mark is ever shown.
- 34px: the site header.
Approved files
Section titled “Approved files”Use only these. Don’t trace, export or redraw your own.

The Chrome extension icon
Section titled “The Chrome extension icon”The extension icon is the gold b alone on a transparent background, from the same vector as logo.svg. No black square behind it. Store and app icons, which need a solid tile, stay as they are. Decided 14 Oct 2026.
The logo as the b in headings
Section titled “The logo as the b in headings”In campaign headings the logo replaces the letter b: “[b] is for business”, “Just [b]”, as on /just-b. The details are on the Type page.
Don’ts
Section titled “Don’ts”- Don’t redraw the mark, or rebuild it from shapes.
- Don’t stretch, squash, skew or rotate it.
- Don’t recolour it, except where a theme recolours theme gold (see Colour).
- Don’t add outlines, strokes, bevels, shadows or other effects. The only effect is the soft gold glow.
- Don’t put an X, a word or another shape inside it.
- Don’t show it enormous on its own. A huge lone b looks unflattering (owner). Pair it with words, or keep it at a modest size.
